Go to this post. The combinations that are being suggested would work for you. I caught Pike in Alaska on an 8 weight and never felt under gunned. I don't know how big the Pike are in Northern Michigan but if they get as large as they do in Canada then you might want a 10 weight. A 9 weight may be a good compromise but an 8 weight would be a better all around rod. Pike are not great runners and unless you are fishing trophy waters, I would not hesitate to use a 8 weight rod. A 9', 8 weight TFO TiCr would be a very good rod. You will need some 6" steel leaders and some big streamer flies and some red and white poppers. Pike in shallow water will tear up a top water.
